Abstract (en)

A display device capable of realizing a desired color temperature is provided. Phosphor layers (5a,5b,5c) which are excited by ultraviolet radiation produced by discharge and emit red, green and blue visible light, are formed inside a red, green and blue gas discharge tube (1a,1b,1c) respectively. The height (Yc) of the phosphor layer (5c) with respect to a rear support body (20) is higher than the heights (Ya,Yb) of the phosphor layers (5a,5b) with respect to the rear support member (20), and establishes the relationship Yc > Ya = Yb. Therefore, the distance from the phosphor layer (5c) to the opposite discharge surface on a front support body is shorter than those from the phosphor layers (5a,5b), the visible light emitted from the display device (10) is shifted toward blue, that is, the color temperature increases.
